COFFEE-MILL.

SPECIFICATION forming part of I ietters Patent No. 413,320, datedOctober 22 1889.

Application filed June 245, 1889.

T0 at whom it may concern:

Be it known that 1, WILLIAM A. HANOE, a citizen of the United States ofAmerica, residing at Freeport, in the county of Stephenson and State ofIllinois, have invented certain new and useful Improvements in Coffee-Mills, of which the following is a description.

' mills, such as are adapted to the ordinary use of the household, andits object is to cheapen the manufacture of these mills, to the end thata perfectly reliable mill may be furnished to the public at agreatly-reduced price.

Referring to the drawings, A is the upper casting or hopper; B, thelower casting or body of the mill, and C the top of the boX or standwhich supports the mill. The bridge or cross-piece D is cast integralwith the part B, and carries the central shaft of the mill at E.

My invention consists in the improved means devised to fasten the partsA and B together and firmly clamp them to the cover 0. In my preferredconstruction I do this by casting two shoulders e e upon the'part E andforming upon the lower edge of the hopper A the armsF F, projectingdownward and inward to meet the shoulders e e. The bearing-surfaces ofthe shoulders and arms are slightly inclined, so that the hopper A canbe shoved down into the position indicated by dotted lines in Fig. 1,and then twisted around into place, the ends of the arms F F beingthereby tightly wedged under the shoulders e e on the bridge D. Toprevent any accidental displacement of these parts, I form a slightdepression f upon the inclined surface of the arm F, into which theshoulder e drops when it reaches the position shown in full lines inFig. 1.

In the manufacture of these mills care should be taken that in putting.the mill together the hopper A be turned or twisted in Serial No.315,333. (No model.)

a direction opposite to that in which the shaft of the mill will berotated when inuse, inasmuch as the force applied to do the latter tendsto turn the casting B with it, and hence, if the above direction beobserved, will twist the parts all the more tightly together.

The modifications that can be made in the above-described constructionwithout departing from my invention are innumerable. For example, theparts may be reversed, the arms F being placed upon the casting B orsome attachment thereof, and the shoulders e 6 upon the casting A.Another form is shown in Fig. 3, in which the provision of separateshoulders e e is dispensed with by extending the arms F F around toengage with the under surface of the bridge D, as seen at G. From theseillustrationsit will be seen that the essential feature of my inventionis the provision upon one of .the castings A B of an inclined bearingsurface or surfaces, and upon the other casting of shoulders againstwhich such bearing-surfaces may be wedged by simply rotating or twistingthe 7 5 one casting upon the other.

The principal advantage of my invention over former constructions is theease with which the mill can be put together by an unskilled workmanwithout the use of any spe- 8o eial tools or appliances. This enablesthe various parts to be made separately after a common pattern, shippedto their destination, and there put together by the dealer.

A glance at the form of the different parts of the mill shows that theycan be packed much more closely before they are put together thanafterward, and hence a greatsaving effected by shipping them in theseparate parts.

In the construction shown in Fig. l-the form which I preferthe elasticforces of the casting 1A and arms F F are combined to exert an upwardpull upon the central portion E of the casting B, thereby keeping theparts properly centered and in position. 5

I claim as new and desire to secure by Letters Patent-- 1. Incombination with the case-cover C, a hopper A, resting thereupon, andbearing arms F F, projecting inward toward the cenroe ter, and a grindin-shell B beneath said cover and having a diam'etrical bridge D, providedupon its central portion with shoulders e e, the bridge D, provided withthe shoulders ee adapted to be engaged with the arms F F upon thecentral portion E thereof, as and 10 by rotating said hopper withreference to said for the purpose stated.

shell, and thereby firmly clamp all of said 5 parts together, as and forthe purpose stated. \VILLIAM A. HANGE.
